<p>A link (11) comprises an upper transportation plane (13) and transverse housings (14) for receiving pivot pins (15) to be hinged with other similar links so as to make a chain conveyor. The link further comprises, below the transportation plane (13), at least one surface (16) resting and sliding on a guide (12) and teeth (19) projecting towards each other in a direction transverse to the link to define a passageway (22) therebetween for receiving at least part of the guide. The teeth (19) are designed to be fitted under corresponding projections (21) in the guide so as to form a slidable engagement along said guide. Said teeth (19) are located close to the side ends of the link in order to include the support and slide surface (17) of the guide. The link comprises seatings (23) into which sliding elements (24) embodying side sliding surfaces (25) of the link along the guide are received. Elements (24) comprise end plugging portions (26) to close the housing (14) ends to prevent the pins from slipping off therefrom. <IMAGE></p> |
